APPARATUS HANDLING GLASSWARE.

Specification of Letters Patent.

Patented Feb. 6,1912.

Application filed June 24, 1908. Serial No. 440,202.

To all whom it may concern:

Be it known that'I, VERGIL MULHQLLAND, a resident of, Edgewood, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Apparatus for Handling Glassware; and I do herebydeclare the following to'be a full, clear, and exact descriptionthereof.

My invention relates to apparatus for handling glassware.

The object of my invention is to provide apparatus for mechanicallylifting the ware from open molds or other receptacles containing theware and depositing the same upon a conveyor by means of which the wareis transferred to the le thereby doing away with the great a I unt oflabor and expense heretofore incurred in doing this work by manuallabor.

To these ends my invention comprises the novel features hereinafter setforth and claimed.

In the drawings Figure 1 is an end elevation partly in section of myimproved apparatus; Fig. 2 is a plan view thereof partly in section; F 3is a side viewof the glass machine and transfer mechanism; Fig. 4 is anenlarged View of the mechanism for transferring'the ware to the leercarrier; Fig. 5 is an enlarged plan view detail partly broken away ofthe last named apparatus;-

Fig. 6 is a like view showing a portion of the transfer apparatus fromthe mold; and Figs. 7, 8 and 9 are enlarged details.

I have illustrated my invention in connection with a common form ofmachine for making glassware, in which the numeral 2 designates the baseor platform mounted on the trucks 3. Mounted on the base 2 is thecentral standard .or column 4 which-carv.pies the revolving table 5,said table carrying the molds 6-which are arranged at intervals thereon.

I have not deemed it necessary to illustrate the mechanism for pressingand blowing the ware, nor the mechanism by' means scope of my inventionthe lifting of the were from any receptacle into which the ware may'havebeen introduced after leaving the mold.

A shaft 7 is journaled in suitable bearings 7 in the frame 8 and on saidshaft is the pulley 9 which is connected up. by the belt 9 to a suitablemotor. On the shaft 7 is the worm 10 which meshes with the worm wheel 11on the shaft 12. A gear wheel 11 on the shaft 6 meshes with the gearwheel 13 on the shaft 14, and a bevel pinion 15 on said shaft mesheswith the bevel pinion 16 on the shaft 172 .A-bevel pinion 18 on theshaft 17 meshes with the bevel pinion 19 on the shaft 20. Mounted on theshaft 20 is the cam wheel 21, which has formed on its periphery the cam22. A second cam wheel 23 on the shaft'20 is also provided with the cam24. A lever 25 is pivoted at 26 to the frame 2 and said lever isprovided with the idle rollers 28 between which the cam 22 is adapted tomove. A link 29 is connected to the lever 25, said link being connectedto the short arm 30 which has the collar 31, keyed to the vertical shaft32.

A lever '33 is pivoted at 34, said lever having the idle rollers 34between which the cam 24 moves. A link 35. is connected to the lever 33and said link is connected to the arm 36, keyed'to the sleeve 37 on theshaft 32. Keyed to the sleeve 37 is the short arm 38. A link 39 isconnected to the short arm fulcrumed at 41 to the frame 42. The frame 42is loosely mounted on the sleeve 37 torotate thereon, but keyed to theshaft 32 by.

means of the feather 43. At the end of the arm 40 is the clevis 44 whichhasthe pins 45 engaging the bifurcated end 46 of the arm 40. Extendingthrough the clevis 44 is the rod 47, and pivoted to the inner end ofsaid rod by the pin 49 extending through the frame 42. spring 50 isinterposed between the head of the rod 47 and the clevis 43, said springacting normally to close the scissor arms 48. to the scissor arms and tothe clevis 43.

' On the shaft '20 is thecam 52 which is adapted to engage the idleroller 53 on the arm 54, said arm being pivoted to the frame at 55.Connectedto the outer end of the arm 54 is the link 56 connected at itsup- Links 51 are connected The frame 64 has the hub portion 66 throughwhich the pin 67 passes and upon which said frame is adapted to swing.The frame 64 hasthe upwardly extending arm 68 and carried by said arm isthe ring 69. 'A finger 70 is pivoted at 71 to the arm 68, as clearlyshown in Fig. 5. A spring 70 is secured at one end to the arm 68 and atthe other end bears against the finger 70.

The frame 72 of the leer conveying apparatus has the permanent shelf 73and the tilting shelf 74. The tilting shelf 74 is pivoted at 7 5 and theinner end of said shelf is weighted as at 76. This weight actsnormallyto throw the shelf up into the position shown in dotted lines in Fig. 4.Below the tilting shelf 74 is the angle 77 which is insulated from saidshelf by insulating material 78. This angle 77 has the electricalcontacts 79 and 80.- A U shaped bar 81 is secured to the frame and hasthe binding screw 82. Wires 83 and 84 are conencted up to the terminals80 and 82 and said wires leadto the solenoid 65. The U shaped piece 81is insulated from V the terminal 82 by means of the insulating material85.

A spring 86 is secured to the hub 58 on the frame 58, said springengaging with the lug 87 and adapted to return the frame 64 to itsnormal position. An adjustable stop 88 is screwed into the lug 89 on theframe 64 and said screw is adapted to bear against the end of the shelf90 which forms partof the frame 58, said shelf forming a support for theroller 61 when the frame 64 swmgs around to the position indicated indotted lines Fig. 5.

At the u per end' of the shaft 59 is the s rocket-w eel 92 which isdriven by the c ain 93. This chain 93 is provided at intervals with theflights 94, with curved arms 95, said arms acting in the mannerhereinafter set forth to convey the ware to the leer along the frame 72.Such a form of conveyer is illustrated in Letters Patent of the UnitedStates No. 842,209, granted to me and C. R. Knapp, on the 29th day ofJanuary, 1907.

When my improved apparatus is in use, when the rotary table 5 carryingthe molds brin s one of the molds around containing the nished articlesuch as a fruit jar, the mold is opened and the scissor arms 48, asindicated in Fig. 2, will engage the neck of the jar. These scissor armsare forced apart by theaction of the arm 40, brought into such positionby the action of the cam 24, through the intermediate arms and linksdescribed so as to be forced open to engage the jar in the manner shown.After the jar has been seized in this manner by the arms 48 the 'cam 22of the cam wheel 21 comes around in such position as to move the arm 25and through the connections described the frame 42 is swung around insuch position as to bring the jar in position over the shelves 73 and74, as shown in Fig. 6. Just prior, however, to the swinging of, theframe 42 into this position the arm 54 is slightly raised by the cam 52so as to lift the link 56 and the frame 42, whereby the jar is liftedslightly from the mold in order to clear the base of the mold when theframe 43 swings outwardly. When the frame 42 has been swung over in suchposition as to bring the jar over the shelves 73 and 74, the cam 52 actsto lower the arm 54 and with it the frame 42, whereby the jar is loweredinto position to restupon the shelves 73 and 74 within the ring 69.-When the jar has been deposited upon the shelves in this manner the cam23 acts through the connections described to open the scissor arms 48and release the jar, while at the same time the cam 22 acts to returnthe frame 42 to the position indicated in Fig. 2, in position to graspthe next jar as it comes around on the revolving table 5. As soon as thejar has been deposited upon the shelves 73 and 74 the weight of said 'arwill act to lower the tilting shelf 74 to t e position indicated in Fig.4 and the lowering of said shelf will make the electric contact betweenthe terminals 79 and the terminal 82, whereby the solenoid 65 isenergized and the arm 62 lowered, which throws -the roller 61 up intoposition to be engaged .by the cam 60. The enlargement of the rotatingcam 60 coming into engagement with the roller 61 acts to swing the frame64 into the osition indicated in dotted lines Fig. 5, w ereupon the jaris moved along the shelves 73 and 74 and the movementof the chain 93 isso timed that one of the curved arms'95 will travel around in positionto move the jar from the shelves and when the stop 96 is reached thefinger will act to open the rin 69 and release said jar and permit it toe received by the flight 94 which will move the jar along the frame 72to the leer. As soon as the jar .has been freed from the frame 64 theenlarged portion of the. cam 60 will have traveled over the roller 65and said frame 64 will then be free to assume its normal position towhich it will be brought by means of the spring 86. Furthermore, just assoon asthe jar leaves the tilting shelf 74 said shelf will be raised bythe weight 76 and the electrical contact broken so that the roller 61will be lowered out of the path of the cam 60 until the next operation.The frame 64 having been returned to its normal position another jar isdeposited upon the shelves by the swinging frame 42 and the operationjust described is repeated.

It is apparent that the apparatus may be arranged to erate in connectionwith a number of di erent molding machines arranged in proximity to theconveyer. In that case the transfer device for each machine would betimed to operate with the others in such a manner as to fill the flightsin succession.

By my invention the jars contained in the molds, or other receptacles,aretransferred quickly to the conveyer and carrier forward to the leerwithout any handling, and as a consequence the liability of breakage isreduced, while at the same time the manual labor-heretofore employed forcarrying the ware from the molds to the leer carrier is dispensed withand the whole operation carried on mechanically. 1
